BILLING-PRESS.

.T 0 all whom it may concern:

Be it known that I, EMMET H. MeMURRY, a citizen of the United States,residing at Marianna, in the county of Lee and State of Arkansas, haveinvented a new and useful Baling-Press, of which the following is aspecification.

This invention relates to baling presses and is more particularly animprovement upon the apparatus described and claimed in Patent No.855,015, granted to me on May 28, 1907.

The invention resides especially in improved power mechanism whereby therotation of a driving element will be caused to operate mechanism toproduce a preliminary compression of the hay or other material suppliedto the press and cause said material to be directed into the path of themain plunger or follower which subsequently completes the compression ofthe material within the pressure box.

Another object is to simplify the construction of power mechanism forproducing the above result and to provide such mechanism which can beconveniently operated, will not easily get out of order and which can bereadily repaired in the event of the breaking of any of the parts.

With these and. other objects in view the invention consists of certainnovel features of construction and combinations of parts Which will behereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings: Figure 1 is a plan view of the mechanism embodying thepresent improvements, the press being shown in connection therewith, andportions thereof being in section. Fig. 2 is a longitudinal sectionthrough the apparatus. Fig. 3 is a central transverse section throughthe press. Fig. 4 Fig. 5 is a plan View of the power transmittingdevices of the preliminary compressing mechanism. Fig. 6 is a transversesection through the guide trough of said mechanism, and showing thedeflecting blocks in end elevation. Fig. 7 is a detail-view of a portionof one of the deflecting blocks and the clutch members cooperatingtherewith. Fig. 8 is a transverse section through a portion of thetrough and showing the guides of the main plunger.

Serial No. 379,065.

Fig. 9 is a view partly in section and partly in elevation of theconnection between the operating element and the clutch actuating cable,the parts being shown in the position assumed at the beginning of themovement of said mechanism. Fig. 10 is a view similar to Fig. 9 showingthe positions assumed by the parts upon the completion of the movementof the clutch actuating mechanism.

Referring to the figures by characters of reference, 1 designates apress box such as shown and described in my patent before mentioned, thesame being provided adjacent its inlet end with laterally extendingrails 2 secured to laterally extending side walls 2. A slidable base 3is mounted on these rails and between the walls 2 and provided at itsends with upstanding walls or followers 4 and 4 suitably braced. One ormore slotted guides 5 are disposed adjacent and above the feed end ofthe press box and movably mounted within these guides are upwardlyextending projections 6 formed upon a partition 7. This partition ismounted to travel above the base 3 and has depending legs 8 designed toproject through slots 9 formed longitudinc ly within the base. Each legextends upward from a carriage 10 provided with anti-friction rollers 11adapted to travel within channel bars 12 disposed beneath the base. Itis obvious that when the follower 4 is disposed adjacent the inlet endof the press box and the follower 4 is located at a distance therefromthe parti tion 7 is free to travel within the guides 5 and the slots 9and this partition is designed to aline with either of the walls of thepress box while one of the followers 4 and 4 is alining with the otherwall thereof.

Extending from the feed end of the press box is a trough-like structure13 which, as shown in Figs. 6 and 8, is provided with a longitudinalslot 14 in the top thereof in which is mounted a slide 15 to which isfastened the stem 16 of plunger 17. Extending longitudinally from theend of the trough 13 arepreferably two beams 18 between which is secureda block 19 constituting the bearing for a pulley 20. A spring 21connects the stem 16 with the fixed block 19 so that the plunger 17 isheld normally withdrawn from the feed end of the press box 1. A crossbeam 21 is connected to the terminals of the beams 18 and a stud 22extends upward from their points of connection and constitutes the pivotfor a sweep 23. A roller 24 is ournaled in each end of the sweep andthese rollers are designed to successively swing into contact with theconcave head 25 of a pitman 26 pivoted to one end of the stem 16. Thishead 25 has an angular-arm 27 extending therefrom and under the path ofthe rollers 24 and a guide stud 28 extends downward from the arm 27 andis designed to travel within an arcuate slot 29 formed in a roller guide30 which is secured to the beams 18 and 21. An arm 31 extends from eachend of the sweep below and beyond the rollers upon the sweep and, asshown in Figs. 9 and 10, this arm is formed preferably with a concaveface 32 for the purpose hereinafter disclosed.

Suitably supported beneath the base 3 ar pulleys 33 which serve tosupport and guide opposite portions of a cable 34 constituting powertransmitting means. The ends of this cable are fastened to opposite endportions of the base 3 preferably by means of hangers 36 extendingdownward from the base. The intermediate portion of the cable forms aloop which extends partly around and is sup ported by the ulley 2Ohereinbefore referred to. This cab c 34 extends through the trough 13and above deflecting blocks 37 disposed within the trough adjacent thebase 3 and those ends of the blocks nearest the pulley 20 are inclinedas shown particularly at 38. Secured to the cable 34 between each pulley33 and the pulley 20 is a block 39 to which is pivotally connectedpreferably two hooks 40 constituting clutch members. The two blocks 39and their hooks are so disposed that while one of the blocks is reachingthe limit of its movement in one direction the hooks of the other block39 move upward on one of the deflecting blocks 37. A clutch member inthe form of a cross head 41 is slidably mounted within the trough andabove the cable 34 and this cross head is provided with an extension 42located below the plane occupied by the cable 34 and fastened by meansof a cable 43 to a coiled spring 44 extending under the press box anddesigned to hold the cross head normally positioned above and betweenthe blocks 37. Another cable 45 is fastened to the extension 42 of thecross head and extends under the pulley 20 and partly around a pulley 46located adja cent one of the terminals of an arcuate guide rail 47secured to the beams 18 and 21. This rail has a curved slot 48 in whicha slide 49 is mounted to travel and said slide has a hanger 50 to whichthe end of cable 45 is secured. An arm 51 is pivotally connected to theslide 49 and carries a roller 52. A spring 53 is fastened to the slideand holds arm 51 normally in contact with a stop pin 54 carried by theslide. hen the arm is in its normal position the roller 52 is supportedwithin the path of the arms 31 on the sweep I will of course be seen byreferring to the drawing that the two arcuate guides 30 and 47 areformed along lines concentric with the stud. 22, the guide 47, however,being located a greater distance from the stud than the guide 30 so thatthe rollers 24 are free to rotate along the concave face of the guide 47without being retarded thereby.

The mechanism herein described is designed to produce a doublecompression of material such as hay or straw which may be fed to thepress. The first of these com )ressions takes place between one of thefollowers 4 and 4 and the movable partition 7, while the second or finalcompression occurs within the box 1 and is produced by the plunger 17.As has heretofore been stated the base 3 is mounted to slide laterallyin relation to the press box and when in either of its positions thepartition 7 alines with one of the side walls of the press box whileeither the end wall 4 or the wall 4 alines with the other side wall ofthe press box. For example, if the parts are in the positions disclosedin Fig. 1 the material to be baled is fed between the walls 2 and thewall 4 and partition 7. The sweep 23 is set in motion by horse power orin any other preferred manner and as one of its rollers swings towardthe beams 18 it will come into contact with the concave face of head 25and cause the pitman 26 to force the stem 16 and plunger 17 forward intothe press box so that any material in the path of the plunger will bedirected into the box. hen the head 25 reaches the limit of its movementalong the arcuate guide 30 the roller 24 will move off of the head andspring 21, which is placed under stress during the forward movement ofthe plunger, promptly pulls backward on the stem 16 so as to quicklyreturn the plunger to its initial position and to bring the head 25 to apoint where it can be contacted by the next roller 24 and the operationabove described repeated. As soon as the plunger returns to its initialposition in the manner described one of the arms 31 moves against theraised roller 52 on slide 49, as shown in Fig. 9, and therefore theslide is caused to move forward within the slot 48 and to pull upon thecable 45. head 41 to pull forward and as this cross head is locatednormally above the blocks 37 and between said blocks and the base 3, asshown in Fig. 1, it is a )parent that during this movement it will ebrought into engagement with those hooks 40 which are resting upon theblock 37. This will be apparent by referring to Fig. 6 wherein the crosshead is shown back of and in position to engage hooks located upon oneofthe debe free to move across said inlet end untilstopped by theextensions 6 coming into contact with the opposite ends of guides 5. Thefurther movement of the base 3 and follower 4 will be independent of thepartition 7 because of the slots 9 which are employed and therefore thematerial which has been placed between the partition and the follower 4will be compressed in the path of the plunger 17, this compressioncontinuing until the follower 4 is brought into position in alinementwith the nearest side wall of the press box. As soon as this compressionbetween the partition 7 and the follower 4 has been accomplished theslide 49, which has been moving within the slot 48, is brought under theroller 55 and said roller will serve to press the arm 51 downward so asto withdraw the roller 52 from the path of arm 31. Said arm willtherefore be free to continue its movement with the sweep while thespring 44 which has been tensioned as aresult of the movement of thecross head 41 and slide 49, will return the slide and cross head totheir initial positions. During this return movement of the cross headit will leave those hooks 40 which were in engagement therewith and will travel back to its initial position, passing over the other set ofhooks 40 which, in the meantime, have been brought into position uponthe other defleeting block 37. The material to be baled can then beplaced between the partition. 7 and the follower 4 and upon therepetition of the operation above described this material will beinitially compressed in the path of the plunger 17.

It will be seen that the mechanism described is very simple, durable,and efficient and produces an'initial as well as a final compression ofthe material in an expeditious manner without adding to the powerrequired to perform either of the operations.
